Prior Art Couple designs with laser pointers directly installed in putter head � Disadvantages: 1) not detachable (can’t use with ANY golf putter) 2) may be difficult to see laser beam due to positioning 3) laser pointer switch on putter (user needs to stop aiming to switch off beam) Design with laser pointer attached to shaft near grip by means of clamp Disadvantages: 1) Bulky and heavy - “destroys the sense of beauty of the golf putter” - affects smoothness of the user’s action 2) complicated to install on golf putter 3) golf putters have various diameters: clamp might cause emitted beam to vibrate or oscillate when in use �

Description � Detachable laser pointer mounted on the golf putter to aim the putter head at the hole. � Training device for golf playing. Uniqueness: v Compact and convenient for carrying by hand v Easily installed v Projects a clear (easy to see) laser beam onto the ground
